致命错误CodeIgniter：找不到类'PHPExcel_IOFactory'

Question

我正在处理一个需要将数据从Excel（.xlsx）文件导入数据库表中的项目。

我已经写代码控制器，import.php：

if($this->input->post('send')=='add'): 
 
    $config['upload_path'] = 'media/result'; 
 
    //Only allow this type of extensions 
 
    $config['allowed_types'] = 'xlsx|csv'; 
 
    $this->load->library('upload', $config); 
 
    // if any error occurs 
 
    if (! $this->upload->do_upload('upload_file1')) 
 
    { 
 
     $error = array('error' => $this->upload->display_errors()); 
 
    } 
 
    //if successfully uploaded the file 
 
    else 
 
    { 
 
     $upload_data = $this->upload->data(); 
 
     $file_name = $upload_data['file_name']; 
 
     //load library phpExcel 
 
     $this->load->library("Excel"); 
 
     //here i used microsoft excel 2007 
 
     $objReader = PHPExcel_IOFactory::createReader('Excel2007'); 
 
     //set to read only 
 
     $objReader->setReadDataOnly(true); 
 
     //load excel file 
 
     $objPHPExcel = $objReader->load('upload/'.$file_name); 
 
     $sheetnumber = 0; 
 
     foreach ($objPHPExcel->getWorksheetIterator() as $sheet) 
 
     { 
 
      $s = $sheet->getTitle(); // get the sheet name 
 
      $sheet= str_replace(' ', '', $s); // remove the spaces between sheet name 
 
      $sheet= strtolower($sheet); 
 
      $objWorksheet = $objPHPExcel->getSheetByName($s); 
 
      $lastRow = $objPHPExcel->setActiveSheetIndex($sheetnumber)->getHighestRow(); 
 
      $sheetnumber++; 
 

 
      if($sheet=='student')// if sheet name is student 
 
      { 
 
       //loop from first data until last data 
 
       for($j=2; $j<=$lastRow; $j++) 
 
       { 
 
        $classement = $objWorksheet->getCellByColumnAndRow(1,$j)->getValue(); 
 
        $dossard = $objWorksheet->getCellByColumnAndRow(2,$j)->getValue(); 
 
        $nom = $objWorksheet->getCellByColumnAndRow(3,$j)->getValue(); 
 
        $sexe = $objWorksheet->getCellByColumnAndRow(4,$j)->getValue(); 
 
        $cat = $objWorksheet->getCellByColumnAndRow(5,$j)->getValue(); 
 
        $pays = $objWorksheet->getCellByColumnAndRow(6,$j)->getValue(); 
 
        $temps = $objWorksheet->getCellByColumnAndRow(7,$j)->getValue(); 
 
        $tempsreel = $objWorksheet->getCellByColumnAndRow(8,$j)->getValue(); 
 
        $ecart = $objWorksheet->getCellByColumnAndRow(9,$j)->getValue(); 
 
        $moyenne = $objWorksheet->getCellByColumnAndRow(10,$j)->getValue(); 
 
        if($classement != '' || $dossard != ''|| $nom != ''|| $sexe != '' || $cat != '' || $pays != '' || $temps != '' || $tempsreel != '' || $ecart != '' || $moyenne != '') 
 
        { 
 
         $excel = array(
 
          'Classement'=>$classement, 
 
          'dossard'=>$dossard, 
 
          'nomprenom'=>$nom, 
 
          'sexe'=>$sexe, 
 
          'cat'=>$cat, 
 
          'pays'=>$pays, 
 
          'temps'=>$temps, 
 
          'temspreel'=>$tempsreel, 
 
          'ecart'=>$ecart, 
 
          'moyenne'=>$moyenne 
 
         ); 
 
         $this->db->insert('mt_result',$excel); 
 
         $result=($this->db->affected_rows()!= 1)? false:true; 
 
         if($result == true) 
 
         { 
 
          $this->session->set_flashdata('msg', 'Member Details Uploaded Successfully'); 
 
          redirect('Result/'); 
 
         } 
 
         else 
 
         { 
 
          $this->session->set_flashdata('msg1', 'Member Details Uploading Failed'); 
 
          redirect('Result/'); 
 
         } 
 
        } 
 
        else 
 
        { 
 
         $this->session->set_flashdata('msg1', 'Failed To Upload!Contents are not Matched'); 
 
         redirect('Result/'); 
 
        } \t \t 
 
       }// loop ends 
 
      } 
 
     } 
 
    } 
 
endif; \t

每当我把这个控制器我收到以下错误：

A PHP Error was encountered

Severity: Error

Message: Class 'PHPExcel_IOFactory' not found

Filename: controllers/Result.php

Line Number: 229

如何解决这个问题？

Answer 1

试着用的$this->Excel->createReader('Excel2007')代替PHPExcel_IOFactory::createReader('Excel2007')
